      context.

AB  - Recognition memory judgments can be influenced by a variety of signals including 
      fluency. Here, we investigated whether the neural correlates of memory illusions 
      (i.e., misattribution of fluency to prior study) can be modulated by fluency 
      context. Using a masked priming/recognition memory paradigm, we found memory 
      illusions for low confidence decisions. When fluency varied randomly across 
      trials, we found reductions in perirhinal cortex (PrC) activity for primed 
      trials, as well as a (pre)cuneus-PrC (BA 35) connectivity. When the fluency 
      context was unchanging, there was increased PrC activity for primed trials, with 
      the (pre)cuneus showing greater connectivity with PrC (BA 36). Thus, our results 
      tentatively suggest two neural mechanisms via which fluency can lead to memory 
      illusions.
